Conﬁguration of DC input Groups

The conﬁguration of the DC input to the inverters provides several different ways to monitor DC input

power and input current.

For bulk monitoring, assign all inverters to DC Input Group 1.

For a system with two or more battery strings, refer to the power system manual for speciﬁc conﬁguration

details.

6.4.3 Set Output

Set the number of inverters in each phase of your

system. Match the AC input phase to the correspond-

ing AC output phase.

1. Number of Modules: Enter the total number

of inverter modules that will be installed for that

phase.

2. Redundancy: Enter the number of inverter

modules that will provide redundant power for

that phase (used to provide system warnings).

3. Phase Shift: Enter the phase shift for each

output group in your system conﬁguration

1 2 3

Single phase ° 0 N/A N/A

Split phase (120/240 V) ° 0 180 N/A

2-pole (120/208) ° 0 120 N/A

3-phase (120/208 V) ° 0 120 240

4. Nominal Output Voltage: Enter 120 for all

phases.

5. Press Submit.

CAUTION!

The value entered in the Nominal Output Voltage eld can change the actual AC output volt-

age of the inverters. Setting this value to anything other than 120 V will render the UL/CSA

approval invalid.
